DESCRIPTION

This specification describes a dedicated I.C. which allows to charge 1 Lilon cell or 3 Nimh cells. The principle used to charge the batteries is the pulsed current, the monitoring is operated by the micro-contoller of the application. This IC integrates one Power Switch and achieves the charge batteries in two different modes charge or precharge.
